create_pmem_region_store() and create_ram_region_store() are identical
with the exception of the region mode. With the addition of DC region
mode this would end up being 3 copies of the same code.
Refactor create_pmem_region_store() and create_ram_region_store() to use
a single common function to be used in subsequent DC code.

NOTE: the tags were kept even though the region/decoder mode had to be
adjusted to move the patch earlier in the series.
Changes:
[Jonathan: Move forward in series to pick up early]
[iweiny: Adjust to be ahead of region/decoder mode change]
